Exceptions

At least one of the days, hours, minutes, or seconds components is outside its valid range.

Examples

The following example uses the Parse method to convert each element in a string array to a TimeSpan value. It changes the current system culture to Croatian - Croatia ("hr-HR") and English - United States ("en-US") to illustrate how the current system culture affects the parsing operation.

Remarks

The s parameter contains a time interval specification in the form:

[ws][-]{ d | [d.]hh:mm[:ss[.ff]] }[ws]

Elements in square brackets ([ and ]) are optional. One selection from the list of alternatives enclosed in braces ({ and }) and separated by vertical bars (|) is required. The following table describes each element.

A culture-sensitive symbol that separates days from hours. The invariant format uses a period (".") character.

hh

Hours, ranging from 0 to 23.

:

The culture-sensitive time separator symbol. The invariant format uses a colon (":") character.

mm

Minutes, ranging from 0 to 59.

ss

Optional seconds, ranging from 0 to 59.

.

A culture-sensitive symbol that separates seconds from fractions of a second. The invariant format uses a period (".") character.

ff

Optional fractional seconds, consisting of one to seven decimal digits.

If the s argument is not a day value only, it must include an hours and a minutes component; other components are optional. If they are present, the values of each time component must fall within a specified range. For example, the value of hh, the hours component, must be between 0 and 23. Because of this, passing "23:00:00" to the Parse method returns a time interval of 23 hours. On the other hand, passing "24:00:00" returns a time interval of 24 days. Because "24" is outside the range of the hours component, it is interpreted as the days component.

The Parse(String) method tries to parse s by using each of the culture-specific formats for the current culture.

Notes to callers

When a time interval component in the string to be parsed contains more than seven digits, parsing operations in the .NET Framework 3.5 and earlier versions may behave differently from parsing operations in the .NET Framework 4 and later versions. In some cases, parsing operations that succeed in the .NET Framework 3.5 and earlier versions may fail and throw an OverflowException in the .NET Framework 4 and later. In other cases, parsing operations that throw a FormatException in the .NET Framework 3.5 and earlier versions may fail and throw an OverflowException in the .NET Framework 4 and later. The following example illustrates both scenarios.

Exceptions

At least one of the days, hours, minutes, or seconds components in input is outside its valid range.

Examples

The following example defines an array of CultureInfo objects, and uses each object in calls to the Parse(String, IFormatProvider) method to parse the elements in a string array. The example illustrates how the conventions of a specific culture influence the formatting operation.

Remarks

The input parameter contains a time interval specification in the form:

[ws][-]{ d | [d.]hh:mm[:ss[.ff]] }[ws]

Elements in square brackets ([ and ]) are optional; one selection from the list of alternatives enclosed in braces ({ and }) and separated by vertical bars (|) is required. The following table describes each element.

A culture-sensitive symbol that separates days from hours. The default value is a period (".") character.

hh

Hours, ranging from 0 to 23.

:

The culture-sensitive time separator symbol.

mm

Minutes, ranging from 0 to 59.

ss

Optional seconds, ranging from 0 to 59.

.

A culture-sensitive symbol that separates seconds from fractions of a second. The default value is a period (".") character.

ff

Optional fractional seconds, consisting of one to seven decimal digits.

If the input argument is not a day value only, it must include an hours and a minutes component; other components are optional. If they are present, the values of each time component must fall within a specified range. For example, the value of hh, the hours component, must be between 0 and 23. Because of this, passing "23:00:00" to the Parse method returns a time interval of 23 hours. On the other hand, passing "24:00:00" returns a time interval of 24 days. Because "24" is outside the range of the hours component, it is interpreted as the days component.

The Parse(String) method tries to parse input by using each of the culture-specific formats for the culture specified by formatProvider.

The formatProvider parameter is an IFormatProvider implementation that provides culture-specific information about the format of the returned string. The formatProvider parameter can be any of the following:

If formatProvider is null, the DateTimeFormatInfo object that is associated with the current culture is used.
